The perfect synergy of all-day comfort geometry and race-ready performance, the Trek Project One Domane SLR 8 Dura-Ace Disc Road Bike is packed with technology to smooth the road and maximise efficiency to stave off fatigue and push hard when it matters.

An IsoSpeed decoupler at the rear combines with IsoSpeed and an IsoCore bar at the front for superior damping whether racing or exploring the road less travelled. With additional clearance enabling wider tyres, this bike is one of the most versatile and capable in the market.

Trek Project One Domane SLR 8 Dura-Ace Disc Road Bike 2019

The Trek Project One Domane SLR 8 Dura-Ace Disc Road Bike is just as at home at the pointy end of a race as it taking on long days exploring new roads. Comfort is key, and with adjustable IsoSpeed technology at the rear, you can customise the ride feel to suit your needs and terrain. At the front there is further damping, and the Bontrager IsoCore Bar works to reduce high-frequency vibrations through the hands and arms. To ensure that the ride still has an edge in race conditions, the Power Transfer Construction optimises the connection between the head tube, down tube, bottom bracket and rear wheel. Performance Cable Routing, three years in development, keeps gear selection smooth and instant, so you will be able to react instantly to changes in the road or when chasing the next breakaway attempt.


  • Adjustable rear IsoSpeed decoupler smooths the ride, improving rider efficiency and comfort. Fine-tune the compliance to suit your ride style or terrain
  • Front IsoSpeed technology brings a new standard of compliance to the front end of the bike. Improved smoothness and balance helps you ride further, faster and stronger
  • Aerospace materials and weight-saving technology of the 600 Series OCLV carbon delivers an industry-leading balance of weight and stiffness
  • Endurance Fit - geometry engineered for long rides yet maintaining a racy edge
  • Additional clearance to take wider tyres allows you to explore new roads in comfort
  • Bontrager IsoCore Bar, with a continuous inner layer of rubber compound reduces vibrations by 20% over standard carbon handlebars
  • Flat Mount hydraulic disc brakes are lighter, cleaner and more elegant, while also providing superior stopping force, whatever the road conditions
  • Optimised geometry through a Power Transfer Construction ensures that you get the most out of every pedal stroke
  • Race-optimised performance cable routing virtually eliminates friction for consistent gear shifting, regardless of conditions
  • Blendr compatible stem technology lets you interchange your gear for customisation and a clean look
